Frictionless operation reduces wear and maintenance, delivering higher cycle rates and lower operating costs in high-duty cycles. The aluminium body keeps weight manageable for quick installation and simpler handling in constrained spaces, while maintaining rugged durability in factory floors. This model’s single-acting design with a 2-3/4 inch nominal diameter and a 45 mm stroke provides strong, reliable actuation within limited travel, enabling precise clamping and release in tight tooling environments. With a theoretical force of 2130 N, it supports demanding short-stroke applications such as gripping, workholding, and rapid actuator retraction, while minimizing footprint. Its high vibration isolation helps protect sensitive machinery from noise and transients, improving process stability and product quality. Installation is straightforward thanks to compact dimensions and standard porting (G1/4), reducing commissioning time and ensuring compatibility with common pneumatic manifolds. The unit operates across a wide temperature and pressure range (-30 to 50 °C, 0 to 8 bar), extending applicability in diverse production lines. Non-magnetic construction broadens suitability for environments where magnetic interference must be avoided, such as certain automation cells and measurement setups. Overall, the PM/31022 aligns with lean manufacturing goals by delivering reliable actuation, reduced maintenance, and easier integration into existing pneumatic systems.

FAQs
Yes. PM/31022 uses a standard G1/4 port and comes in an aluminium body suitable for mounting to common industrial manifolds. Its compact dimensions and non-magnetic construction simplify integration in tight spaces. When installing, verify thread standards and gasket compatibility to ensure a leak-free, reliable connection in your specific manifold configuration.
The PM/31022 provides a 45 mm (1-3/4 in) stroke and a nominal diameter of 2-3/4 inches. It delivers a theoretical force of 2130 N, optimized for short-stroke, high-force actuation. Real-world performance depends on supply pressure and load; design considerations should include bore alignment and preload to achieve consistent results.
Yes. Its compact footprint, short stroke, and high force make it well-suited for clamping, workholding, and rapid actuation in automated tooling. The aluminium body keeps weight manageable for integrated fixtures, while the single-acting design reduces complexity in vacuum or spring-return configurations. Proper mounting and sealing ensure repeatable clamping force in production environments.
Certifications such as CE, SIL, or IP ratings are not listed in the provided data for PM/31022. To ensure compliance for your application, consult the supplier or distributor for the latest certification documentation and test results. Verification is essential for industries with strict regulatory requirements or where safety-critical actuation is involved.
PM/31022 is designed for maintenance-free operation by eliminating lubrication needs, reducing downtime and ongoing part wear. The frictionless actuation minimizes energy losses and extends component life. Combined with a compact installation footprint and easy integration, this translates to lower total cost of ownership, shorter commissioning times, and improved overall equipment effectiveness (OEE).
